Definitions:

Linear Force

Linear force refers to a force acting in a straight line, as opposed to rotational force, affecting the motion of objects in the direction of the force applied.

Mechanical Advantage

Mechanical Advantage is a concept in physics and engineering describing the factor by which a mechanism multiplies the force or torque applied to it, making it easier to perform work.

Brake Free Stroke

The distance or movement a brake lever or pedal undergoes before the brake mechanism engages and begins to apply stopping force.

Air Compressors

Mechanical devices that increase the pressure of air by reducing its volume, commonly used in various industrial and personal applications.
